The closest we can come to describing Zen in words may be as follows:
• Zen is more of an attitude than a belief.
• Zen is the peace that comes from being one with an entity other than yourself.
• Zen means being aware of your oneness with the world and everything in it.
• Zen means living in the present and experience this reality fully.
• Zen means being free of the distractions and illusory conflicts of the material world.
• Zen means being in the flow of the universe.
• Zen means experiencing fully the present, and delighting in the basic miracle of life itself.

I exclude Buddhism from my definition of Zen, I am currently not interested in that part.

Through time and thought of man, in search for meaning through meditation, Zen is a very good example of how history has shaped language and how the original Sanscrit term ‘dhyana’ entered the Chinese language through the doors of an Indian monk who started his own meditation school “Chan”, which was the word ‘dhyana’ in Chinese pronounciation, transformed from ‘chan-na’, and at the end being reduced to ‘Chan’, which then was pronounced “ZEN”.

For some that’s the change they want to see in this world, and perhaps even a manifestation of Buddha’s enlightenment.
